Add variable fallback to fix Chrome issue (#15003)
This works around an issue in Chrome where `::selection` does not read
from variables defined on `::selection` thus breaking all uses of color
utilities with the selection variant. e.g. `selection::bg-red-200`.

We now add a fallback value of `1` to all uses of
`var(--tw-bg-opacity)`, `var(--tw-text-opacity)`,
`var(--tw-border-opacity)`, etc… since Chrome treats the variable as if
it did not exist because it's not defined on the parent.

In Chrome 131 (until the change is rolled back) existing utilities like
these will not work:
- `selection:text-opacity-50`
- `selection:[--tw-text-opacity:0.5]`

Fixes #15000
